Strange - windows dropped by a 1/4 inch....

......whilst switched off and locked.

I locked the car yesterday (E92 M3), after getting something from inside. Definitely did not touch either the driver's or the passenger's side windows.

Yet, I walk past it today, and see rain drops running down the inside surface of the window glass.

I check each side, and both glasses have dropped by about a 1/4 of an inch, enough to allow some rain inside.

Very strange....

Soft close + ice= slightly open windows.

It was not icy when I closed the doors, and I am careful to make sure they are properly closed.

Could it be a faulty door switch leaving the window system thinking that the door isn't fully closed, thus lowering the window partially?

On both sides, at the same time?

Seems a bit unlikely to me.

Does it have press and hold to unlock and drop the Windows?

That was disabled as part of the security update, a few years ago,
